An American commando was killed on Friday in an attack in southern Somalia that also wounded four US military personnel along with a Somali soldier, officials said.
The attack occurred in Jubaland, where a large force comprising about 800 Somali, Kenyan and US troops were working to clear a large area of Al-Qaeda-aligned Al Shabaab fighters.
Since 2007, Al Shabaab has been fighting to overthrow the internationally backed government in Somalia.
